At this point, you may be thinking, “I'm not a high-value military target or part of a warring drug cartel, so I shouldn't have any reason to care about signal jammers.” However, this is certainly not the case. Signal jammers are inexpensive, easy to use, and readily available online to those who know where to look. They can affect your daily life in several ways — veteran-owned surveillance gear manufacturer jammer mart posted some surprising demonstrations on Instagram to prove this point.
The first demo video clip shows how a portable military signal jammer can be tuned to the frequency of a car keyfob, blocking its signal at the flip of a switch. This means a thief could watch you park your car, turn on the jammer before you press the lock button on the fob, and prevent your car from locking. Unless you happened to notice the absence of a click or light flash from your vehicle, you'd probably assume it locked and walk away, allowing the criminal to steal any valuables in the car (or take the car itself).
Another video shows how a jammer can be used to interrupt a wireless doorbell camera by blocking its ability to communicate with the home's WiFi network. Unless the camera has a hardwired data connection — unlike most Ring, Blink, Wyze, and Nest doorbell cams — it will be unable to transmit footage to cloud servers or alert the homeowner that someone is at the door.
There are many other possible applications of wireless military signal jammers, from covertly blocking cell phone calls to disabling GPS tracking devices. These uses are illegal, but as we know, motivated criminals are unlikely to give a second thought to laws and FCC regulations.
